Every year, people across the U.S. ring in the anniversary of America’s independence with music, cookouts and fantastic pyrotechnic displays.

Fireworks have been a central part of the Fourth of July since they were first authorized by Congress for celebrations on July 4, 1777. That first fireworks show consisted of 13 rockets, one for each of the original thirteen colonies.

Even John Adams was an early fan of using rockets to celebrate American independence. In a letter he wrote to his wife in July 1776, Adams declared that the Fourth “ought to be solemnized with Pomp and Parade, with Shews, Games, Sports, Guns, Bells, Bonfires and Illuminations from one End of this Continent to the other from this Time forward forever more.”

Since then, fireworks have turned into quite the tradition, with around 14,000 displays across the U.S. America’s largest Fourth of July fireworks display, put on by Macy’s every year in New York City, sets off 1,600 shells a minute for 26 minutes, and is estimated to cost upwards of $6 million.
